Aston Martin DBX707

The case for the DBX707

The DBX707 is not a trim package; it is a fundamental rework of the DBX. Power from the AMG 4.0-litre twin-turbo V8 rises to 697 bhp, the brakes are carbon-ceramic as standard, the suspension and four-wheel-drive system are recalibrated, and the body gains aggressive aerodynamic additions. At launch it was the world's most powerful luxury SUV.

The result is extraordinary: a 2.2-tonne SUV that accelerates to 62 mph in 3.3 seconds and handles with genuine agility. It is widely regarded as the best-driving super-SUV, ahead of the Urus and Cayenne Turbo GT for driver engagement.

What it costs to run

Running costs are at the top of the SUV scale. Main-dealer servicing is premium, though fixed-price plans exist for newer cars. Carbon-ceramic brakes are durable but extremely expensive to replace. The 22 and 23-inch tyres are costly. Fuel economy is 15 to 20 mpg. Insurance and warranty costs reflect a car that lists from around £190,000.

The AMG engine is well proven, which helps. Most DBX707s are still under manufacturer warranty.

Known weak points

The DBX707 is too new for pattern failures to be established. The DBX platform's early software issues were largely resolved by the time the 707 launched, but verify update status. Carbon-ceramic brakes should be inspected for condition on any used example. The complex air suspension and active systems need to be exercised regularly; a stored super-SUV is a future bill. Check for kerb damage to the large wheels and stone chips on the wide body.

What to check before buying

Full main-dealer history and remaining warranty should be verified. Confirm all software updates and campaigns. Inspect the carbon-ceramic brakes, wheels and bodywork. Test the air suspension through its modes and check every electrical and driver-assistance function. On a car this young and expensive, any accident history should be documented and properly repaired.

Market and depreciation

The DBX707 is early in its depreciation curve. Used examples now trade from around £150,000 to £175,000. Depreciation will continue, as it does for all modern super-SUVs, but the 707's status as the driver's choice in the class should support values relative to rivals. Buy it because you want to drive it, not as an investment.

Who it suits

The buyer who wants the fastest, best-driving super-SUV and can afford the running costs and near-term depreciation. It is a genuinely special car that happens to have four doors and a boot.

Alternatives

Lamborghini Urus Performante, Porsche Cayenne Turbo GT, Ferrari Purosangue at much higher cost, or a standard DBX for better value.

The DBX707, launched in 2022, transforms the DBX formula with 697hp, making it one of the most powerful SUVs available. Beyond the power, it adds standard carbon-ceramic brakes, a revised chassis with retuned air suspension, and subtle styling changes. The result is a genuinely remarkable car that handles with a precision that defies its size and weight, while remaining comfortable enough for daily use.

The carbon-ceramic brakes are a key inspection item: they offer immense performance but very high replacement cost, so have discs and pads measured properly. The more aggressive performance also means tyres wear faster and cost more. Verify the service history is complete and that the car has received all software updates and recalls applicable to its build date.

Values hold firmer than the standard DBX, reflecting the 707's status as the definitive version. The premium is justified by the transformation in capability. Buy the best-documented car, prioritise remaining warranty, and budget for the running costs of a 700hp SUV, which are significant. For the buyer who wants one car that does everything with genuine Aston character, the 707 is the answer; just do not mistake it for an inexpensive ownership proposition.

Against rivals such as the Lamborghini Urus and Porsche Cayenne Turbo GT, the DBX707 offers a distinctly British character: less aggressive than the Lamborghini, more characterful than the Porsche, and with a driving experience that is genuinely remarkable for a car of its size. The 697hp output makes it one of the fastest SUVs ever built, and the chassis work means it handles with a precision that defies its mass.

Running costs reflect the 707's status as the range flagship: the carbon-ceramic brakes, larger tyres and more powerful engine all carry premium costs. Insurance is significant, and fuel consumption is considerable even by SUV standards. The buying priorities are documentation, remaining warranty and evidence of careful use. The DBX707 is the definitive version of Aston Martin's SUV and a genuinely impressive achievement; for the buyer who wants the ultimate DBX, it is the clear choice, and its capabilities justify its position at the top of the range.

The 707 has been widely praised as one of the best high-performance SUVs ever built, and the praise is justified. The transformation over the standard DBX is genuine, and the car's capabilities are remarkable. For the buyer who can accommodate the running costs and wants one car that does everything at the highest level, the DBX707 is a convincing answer. Buy a documented car with remaining warranty and evidence of careful use, and it will provide a genuinely extraordinary ownership experience.
